WHY SHOULD I EVEN CARE ABOUT MPLS? • SCALABILITY • TRAFFIC ENGINEERING • QOS • REDUNDANCY • INDEPENDENT OF LAYER 2 AND LAYER 3 PROTOCOLS • BUT I CAN DO THIS WITH OSPF AND BGP ALREADY?

I WILL HELP YOU FOR FREE YOU POOR B@$%!RD. • ARE STATIC ROUTES BAD? • NO, JUST NOT SCALABLE • IF YOU ARE RUNNING STATIC ROUTES COMFORTABLY YOU PROBABLY DON’T HAVE A NEED FOR MPLS
DRAWBACKS TO MPLS • MORE ADMINISTRATIVE OVERHEAD • LARGER MTUS NEEDED • INCREASED NETWORK COMPLEXITY • CHANGE IS SCARY • DO I REALLY NEED MPLS?
MPLS SECURITY • EASY TO SPOOF IP ADDRESSES, ALMOST IMPOSSIBLE TO SPOOF LABELS • EVERY PE ROUTER MAINTAINS A SEPARATE BRF • DOES NOT DO ENCRYPTION OR AUTHENTICATION • MOST ATTACKS ARE AGAINST THE PE ROUTER OR THE ROUTING ON TOP OF MPLS
VPLS • VPLS CAN HELP YOU SAVE IP ADDRESSES • TUNNEL BACK TO A CENTRAL CORE WHERE A SINGLE POOL CAN ASSIGN IPS • WILL EOIP DO THE SAME FOR ME?
